TR 1737-16 Functional Rating Checklist Summary
Functional Rating • ID Team’s determination/discussion • For an area to be PFC means it provides the elements contained in the definition – dissipates energies, filters sediment, aids floodplain development, etc.
Functional Rating cont. • If all the items on the checklist are answered yes, obviously it is PFC. • If there are some no responses the ID team must determine if any of these answers make the area susceptible to degradation from energy events.
Functional Rating cont. • If the no answers can result in degradation the area is rated something less than PFC. • Functional-at-risk areas will possess some or even most of the elements in the definition but have at least one attribute/process that gives it a high probability of degradation with energy events.
Functional Rating cont. • Trend must be determined when a rating of functional-at-risk is given • Nonfunctional areas clearly lack the elements listed in PFC. Usually these areas have a preponderance of no answers.
